VAL-MATIC'S SURGEBUSTER CHECK VALVE OPERATION, MAINTENANCE AND INSTALLATION INTRODUCTION The Surgebuster Check Valve has been designed to give years of trouble-free operation. This manual will provide you with the information needed to properly install and maintain the valve and to ensure a long service life. The valve is opened by the fluid flow in one direction and closes automatically to prevent flow in the reverse direction.
INSTALLATION VALVE CONSTRUCTION Correct installation of the Surgebuster is important for proper operation. It may be installed in either horizontal or vertical flow-up applications. However, when horizontal, the valve must be installed with the nameplate facing up and the cover level. In all installations, the flow arrow cast in the valve cover must be pointed in the direction of flow during normal system operation.
TROUBLESHOOTING RE-ASSEMBLY Several problems and solutions are presented below to assist you in troubleshooting the valve assembly in an efficient manner. All parts must be cleaned. Gasket surfaces should be cleaned with a stiff wire brush in the direction of the serrations or machine marks. Worn parts, gaskets and seals should be replaced during reassembly. Leakage at Bottom Actuator: Remove line pressure and exercise actuator.
BACKFLOW ACTUATOR FIELD INSTALLATION AND MAINTENANCE (OPTIONAL) the valve by turning the brass bushing (6) counterclockwise. Disassemble the actuator as follows: BACKFLOW ACTUATOR OPERATION: An optional backflow actuator assembly is available which can be easily installed in the field. The actuator is not designed to operate at the valve’s Maximum Working Pressure rating. Therefore, prior to using the actuator, close the pump isolation valve and bleed off line pressure.
MECHANICAL INDICATOR (OPTIONAL) The mechanical indicator is an option that fits into the cover and can easily be installed in the field by going through the following steps. The mechanical indicator is used to visually indicate when the valve is opened or closed. 1. Remove line pressure and drain valve. WARNING Removal of the pipe plug while under pressure may cause bodily harm. 2. Score the coating around and remove the pipe plug from the cover. 3. Apply pipe joint compound to indicator body (21) threads.
BOTTOM MOUNTED OIL DASHPOT FIELD INSTALLATION AND MAINTENANCE (OPTIONAL) DASHPOT FIELD INSTALLATION: The bottom dashpot is supplied as an optional assembly from the factory. This unit provides control of the disc’s final 10% travel to the closed position to reduce valve slam and water hammer. The 10% travel time is adjustable between 1 and 5 seconds. CHECKING OIL AND GREASE LEVELS: 1. The check valve should be closed. 1. Depressurize and drain the valve and pipeline. 3.
HANDPUMP OPERATION: The Dashpot may be equipped with a hand pump as shown in Figure 7. The hand pump can be used to drive the valve partially open using hydraulic oil pressure. 1. To open the Check Valve, close the round Release Knob (turn clockwise 3 turns), insert the pump handle into the pump, and stroke the pump several times. 2. To close the Check Valve, open the Release Knob (turn counterclockwise 3 turns) to release the oil pressure. Hand pump: Simplex Series P1000. FIGURE 7.
VAL-MATIC SURGEBUSTER LIMITED WARRANTY Val-Matic Valve and Manufacturing Corporation warrants the Surgebuster to outperform any manufacturer’s normally equipped Air Cushion, Weight and Lever Swing Check Valve with respect to surge pressure normally generated by check valve closure for installations within the manufacturer’s published ratings of the valve with regard to pressure, temperature and installation orientation.
